Ubuntu – How To Uninstall Failed ‘dpkg -i xorg_7.6+12ubuntu1_amd64.deb’ Command

I was attempting to fix a dual monitor issue with an install of Ubuntu 12.04 64 bit on a Sony Vaio VGN-NS135E.

I ran the following command (downloaded the deb from – https://launchpad.net/ubuntu/+source/xorg/1:7.6+12ubuntu1/+build/3309759):

sudo dpkg -i xorg_7.6+12ubuntu1_amd64.deb

Because I was frustrated and was told in a few posts that reverting xorg might help. I somehow ended up fixing the monitor issue I was having but now I get the issue of this failed install. (Monitor is now working btw, once I rebooted with the monitor plugged in before boot.)

My error now is that I have a partially configured xorg package and seemingly no way to remove it. I also cannot open the Software Center without it wanting to repair and the repair fails for the same reason as the next code block. Here is output from sudo apt-get autoremove:

sudo apt-get autoremove

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 xorg : Depends: xserver-xorg (>= 1:7.6+12ubuntu1)
E: Unmet dependencies. Try using -f.

I've attempted all of the commands on the post: How do I force configuration of partially installed packages?

Here is the output from sudo apt-get install -f:
